基于Multisim的正弦稳态电路仿真分析

Simulation of Sinusoidal Steady-State Circuit Based on Multisim

正弦稳态电路采用相量分析法,分析步骤与结果都比较抽象,不便于学生理解.通过具体实例,利用Multisim软件的万用表、示波器、探针和波特仪等虚拟仪器,以及交流分析功能实现了正弦电流的幅度与初相位的测量,与理论分析结果一致.同时Multisim将正弦交流信号的波形直观显示出来.灵活运用Multisim软件仿真分析功能,能够使正弦稳态电路的分析具体化,从而提高学习效果.

Adopting phasor method,,the analysis steps and results of the sinusoidal steady-state circuit are relatively abstract,which is not easy for students to understand.Through specific examples,the amplitude and initial phase of sinusoidal current are measured by using virtual instruments such as multimeter,oscilloscope,measure probe and bode plotter of Multisim as well as AC analysis,which is consistent with the theoretical analysis results.At the same time,Multisim could display the waveform of the sinusoidal AC signal visually.The simulation of Multisim can make the analysis of sinusoidal steady-state circuit concrete,and enable students to combine theoretical analysis with practice.
